07KR51 1SBP260011R1001 With the PCI Express bus in widespread use and new processors and chipsets no longer supporting ISA, the industry needed a completely new design concept: COM Express, a specification that was relatively easy to develop, but not easy. PICMG, which presided over the standardization, had to fight off internal obstacles and delays.

07KR51 1SBP260011R1001 The embedded computer industry agreed on PICMG’s COM Express standard. The concept, which had been developed in collaboration with Intel in the fall of 2003, took 18 months to standardize. Christian Eder, the drafter, has led the development of the standard.

07KR51 1SBP260011R1001 can offer a wide range of COM Express modules. That said, the ETX/XTX modules have not gone away, which means that the first computer-on-module (COM) cycle is not yet over.COM Express spent many years catching up with ETX/XTX, and it wasn’t until 2012 that it finally overtook the latter in terms of numbers. It seems that the adage “if it works well, don’t change it” is popular not only in the embedded computer market.
